CVE-2026-86109
HIGH 7.5 ALL-YEARSThe VeloCloud Edge software update workflow may accept update bundles without properly validating their signatures because the workflow does not restrict the digest algorithm used for artifact verification. An attacker with either sufficient privileges to upload packages to VeloCloud Orchestrator or credentials permitting direct access to an Edge may be able to install unauthorized software.
Severe if exploited (CVSS 7.5), but no confirmed exploitation. Patch on a normal cadence.
